NASA's Bennu samples reveal sugars, gum, and stardust

NASA's OSIRIS-REx mission brought back samples from an asteroid named Bennu.

Scientists found important sugars like ribose and glucose, which are parts of RNA and DNA.

They also discovered a strange, gum-like substance rich in nitrogen and oxygen, and tiny bits of stardust from before our solar system existed.

These findings suggest that the building blocks of life might have been present in the early solar system.

The sugars and other molecules could have helped life start on Earth.

The stardust shows that some materials remained unchanged even as the asteroid evolved.
